Embodiment 1

[0010] The working principle of the present invention: the main function of the stepless lifting six-dimensional force sensor calibration device is to provide standard generalized loading, and use the standard generalized load to calibrate the static performance indicators of the six-dimensional force sensor. The lifting pulley is moved to a certain position and fixed by the pulley stepless lifting mechanism 4, and then the loading is started, and the output torque M is generated through the manual loading reducer 3, and the loading rope 7 is wound on the reel of the reducer 3, thereby generating a rope The tension K of the tension force K is proportional to the input torque of the hand crank, and its magnitude is detected by the standard tension sensor 8; the loading rope 7 changes the loading direction through the upper pulley and the lower pulley on the support frame 2, and the loading rope 7 The angle θ with the horizontal plane is detected by the inclination sensor 9; by c...

Abstract

The stepless lifting 6D force sensor calibrating device features the portal supporting frame fixed vertically on the platform, the stepless lifting mechanism comprising speed reducer and pulley and installed onto the portal supporting frame, and the 6D force sensor with upper end fixed on the platform and the upper end with circular ring connected via screw to the auxiliary coordinate frame. Compared with available technology, the present invention has the advantages of capacity of generalized loading and calibration on multidimensional force sensor; large speed ratio reducer applying load and stepless pulley lifting mechanism for obtaining the horizontal angle of the rope of different load, precisely measuring the angle with inclination sensor and precisely calculating loads in different directions; and capacity of calibrating large size and large range force sensor.

Description

technical field [0001] The invention relates to a generalized force loading, in particular to a stepless lifting type six-dimensional force sensor calibration device. Background technique [0002] At present, the calibration of force sensors usually adopts the loading method of applying standard weights. This method can only calibrate the sensor in one direction, which is neither suitable for multi-dimensional force sensor calibration nor large-range sensor calibration. . Although the applied load can be amplified under a certain amount of loading weights through the principle of leverage, this kind of load amplification will affect the loading accuracy of the sensor, and the calibration of the multi-dimensional force sensor's anisotropic torque is inaccurate, unsystematic, and not applicable It is suitable for generalized loading and calibration of large-scale sensors. Contents of the invention [0003] The purpose of the present invention is to provide a stepless lifti...
